“Keep making people laugh,” he posted on the site. “Don’t watch the season 2 opener of ‘House of Cards.’ ”

In that episode, reporter Zoe Barnes, played by Kate Mara, is pushed in front of a speeding train by Frank Underwood, Kevin Spacey’s character.

Brooklyn video editor Minnie Bennet, 25, said she has mutual friends with Dye and decided to donate after learning on Facebook what had happened.

“When I read the article about how she tweeted a thumbs-up when she was OK, I thought that was really cool,” she said.

“Her comedy really has a ‘me too’ feeling about it. You’re with her.”

Dye’s Web site received so many donations Sunday that it crashed for about six hours.“All comedians can really identify with this,” said Lee, a stand-up comic who has appeared on Comedy Central and VH1. “We all moved to New York with nothing in our pockets and a dream.”

A benefit was also held the same day at the Upright Citizens Brigade Theater.

Another fund-raiser will be held March 5 at The Stand in Gramercy, and will feature comedians such as Janeane Garofalo, Pete Lee and Amanda Seales.
